Japan plans real-world diesel emissions test after companies fail

Japan's transport ministry plans to start real-world diesel emissions tests after an experiment found four models from Toyota, Nissan, and Mitsubishi that produced more nitrogen oxide (NOx) emissions than the nation's rules allow, according to The Japan Times. Regulators there usually only perform emissions checks in the lab. The VW diesel scandal has everyone double-checking their figures. Diesel versions of the Toyota Hiace van, Land Cruiser Prado, and Nissan X-Trail produced up to 10 times more NOx than allowed. The Mitsubishi Delica D:5 was up to five times over the limit, The Wall Street Journal reports. There was no evidence of defeat devices in the vehicles. Mazda performed well in the experiment, though. The CX-5 passed with nearly the same results on the road and in the lab. The Demio, better known as the Mazda2, did nearly as well with only slighter higher figures in the real world than in the controlled setting. The experimenters theorized the reason for the excessive emissions was that cold weather caused the engines' software to shut off the exhaust gas recirculation to prevent damage, according to the WSJ. However, this behavior also increased NOx production. Toyota, Nissan, and Mitsubishi don't have to worry about punishment from the transport ministry because this check was just an experiment. Their models already passed the mandated lab tests, which was the only requirement, according to The Japan Times. As governments begin greater real-world emissions tests, the results suggests diesels aren't very clean. A recent check in France found models from Ford, Renault, and Mercedes-Benz that didn't perform up to the standards. Regulators in India conducted similar evaluations and ordered VW to recall over 300,000 vehicles. Related Video:

Nissan gives us the business on the art of clay modeling

The team from The Dashboard recently stopped by the Nissan Technical Center in Japan for a look at what exactly goes into creating a full-scale clay model. While automakers have been using clay bucks for decades, designers and engineers are now combining computer renderings and hand-sculpted clay models to determine how a new vehicle will look in our world. Engineers use specially formulated clay kept warm in an oven to bring the body panels to life. They then coat the clay in a thin plastic film to add body color for the final look.
By the time everything is said and done, workers may have hundreds of hours in the model's creation. So, what happens when the company no longer needs the buck? They get scrapped. Someone comes in and dismantles the whole creation. We presume that action is set to the wailing tears of everyone who had a hand in building the model. Check out the video below for a closer look.

Next Nissan Titan will get turbocharged diesel V8 from Cummins

Toyota might be content to eke out an existence in the fullsize pickup market with its lightly refreshed Tundra, but Nissan looks like it'll be a bit more aggressive with its next-generation Titan. The next Titan will make use of a 5.0-liter, turbodiesel V8 from Cummins, the Japanese company announced at the start of its Nissan 360 industry showcase.
Nissan's commitment to a fullsize pickup isn't really open for debate - it made waves back in April when it lured Fred Diaz, CEO of Chrysler's Ram pickup division, down to its Franklin, Tennessee headquarters. But this news of a monster turbodiesel is big. As of this writing, only Ram is set to offer a diesel engine in a non-heavy-duty pickup. Its 3.0-liter, EcoDiesel V6 will arrive in the Ram 1500 in the not-so-distant future, but that engine will still be a far cry from what's promised with this Cummins mill.
The 5.0-liter V8 is expected to generate well over 500 pound-feet of torque - likely closer to 550, based on the language in the press release - along with over 300 horsepower. Those figures aren't just a shot across the bow of Ford, Chevy, GMC and Ram, they're an opening broadside, meant to demonstrate Nissan's willingness with its next light-duty truck. As Diaz said, "There is no question that the new Titan will turn heads, and with the available Cummins 5.0-liter V8 turbodiesel, we expect to win new fans and attract buyers looking for this unique configuration."
